CloudStream Extend v1.3.0 - plugins moved to their own repo, in-app updates retargeted

CloudStream Extend v1.3.0

Plugin set moved to its own repository, and in-app updates now come from this repo.

Extensions now live in cloudstream-extend-plugins

All plugin source and the built .cs3 packages moved there, so plugins are released and
updated independently of the app. Install them from Settings → Extensions → Add repository:

Plugin	Needs
HiAnime, AniKoto, AnimeCube, HDHub4u	nothing — they stream directly
BollyFlix, YTS	a debrid account (Torrin / TorBox / Real-Debrid)
Torrin, Torrin MDBList, Torrin Trakt	debrid + a free TMDB key

Other changes

• In-app "check for updates" points at this repository instead of upstream
• Plugin repositories are no longer built from the app tree

Note on this build

This is the same debug-signed build as the previous releases, so:

• the package is com.lagradost.cloudstream3.debug (installs alongside a release build, does not replace it)
• the in-app updater stays disabled in it — that check is compiled out for debug builds

A signed release build needs SIGNING_KEY_ALIAS, SIGNING_STORE_PASSWORD,
SIGNING_KEY_PASSWORD and a keystore in %USERPROFILE%/work/_temp/keystore/.

Also worth knowing for future releases: the updater reads the version from the
asset file name (it must look like ...-4.9.3.apk) and compares it with the
installed app's versionName — so keep the asset name carrying the app version,
not the release tag.
